Abstract
La présente invention concerne un procédé de polissage d'articles acryliques comprenant des matières acryliques souples. Le procédé comporte une opération de polissage cryogénique et une opération de nettoyage. L'opération de polissage consiste à mettre dans un récipient des billes à polir de différents calibres, du bicarbonate de sodium, un agent de gonflement et les articles à polir, et ce, pendant une durée, et à une vitesse de rotation, suffisantes pour éliminer de la surface les irrégularités. Après l'opération de polissage, le procédé consiste à mettre dans un récipient (a) une boue liquide comprenant des billes de nettoyage de différents calibres et (i) de la soude caustique et de l'eau ou (ii) de l'alumine, un agent tensio-actif et un solvant, et (b) les articles à nettoyer, et ce, pendant une durée, et à une vitesse de rotation, suffisantes pour nettoyer la surface des articles polis. On assure de préférence une agitation au moyen d'un tambour culbuteur.
